Abstract

SE PROPONE UN PROCEDIMIENTO PARA LA INVESTIGACION DE UN GAS, DONDE EL GAS A SER INVESTIGADO SE GUIA A TRAVES DE UNA DISPOSICION (13) DE MEDICION, QUE ESTA SUJETA A UN ENSUCIAMIENTO POR MEDIO DE PARTICULAS DEL GAS A SER INVESTIGADO. SE PROPONE UNA DETERMINACION DE LA CONCENTRACION DE CO2 EN EL GAS NO DILUIDO, QUE A CONTINUACION SE MEZCLA CON EL AIRE (15) DEL MEDIO AMBIENTE, DETERMINANDOSE DE NUEVO LA CONCENTRACION EN EL GAS DILUIDO DE CO2. EL RESULTADO (28) DE INVESTIGACION DETERMINADO A PARTIR DE LA DISPOSICION (13) DE MEDICION SE CORRIGE EN DEPENDENCIA DE AMBOS RESULTADOS DE LAS MEDICIONES DE CONCENTRACION DE CO2. EL PROCEDIMIENTO DE ACUERDO CON LA INVENCION ES APROPIADO PARA LA INVESTIGACION DE GASES QUE ESCAPE QUE CONTIENEN HOLLIN, EN PARTICULAR DE GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA DIESEL.A PROPOSED PROCEDURE FOR THE INVESTIGATION OF A GAS IS PROPOSED, WHERE THE GAS TO BE INVESTIGATED IS GUIDED THROUGH A MEASURING PROVISION (13), WHICH IS SUBJECT TO DIRTING BY GAS PARTICLES TO BE INVESTIGATED. A DETERMINATION OF THE CO2 CONCENTRATION IN THE UNDILUTED GAS IS PROPOSED, WHICH IS THEN MIXED WITH THE AIR (15) OF THE ENVIRONMENT, DETERMINING AGAIN THE CONCENTRATION IN THE CO2 DILUTED GAS. THE RESEARCH RESULT (28) DETERMINED FROM MEASUREMENT PROVISION (13) IS CORRECTED DEPENDING ON BOTH RESULTS OF CO2 CONCENTRATION MEASUREMENTS. THE PROCEDURE ACCORDING TO THE INVENTION IS APPROPRIATE FOR THE INVESTIGATION OF EXHAUST GASES CONTAINING HOLLIN, IN PARTICULAR OF EXHAUST GASES FROM AN INTERNAL DIESEL COMBUSTION ENGINE.
